Abstract
The invention provides a heat-preserving and anti-freezing liquid conveying pipe. The conveying pipe is characterized by consisting of three layers, wherein an outermost layer is a rock wool heat-preserving layer which is fixed to the outermost layer in a ring flange press mounting way; a middle layer is filled with anti-freezing liquid; an innermost layer is a liquid channel. The heat-preserving and anti-freezing liquid conveying pipe has the advantages and beneficial effects that according to the technical scheme, the rock wool heat-preserving layer coats the outermost layer in a ring flange press mounting way, and can be replaced conveniently by only opening a flange, and the appearance is attractive; the middle layer is filled with the anti-freezing liquid, so that cold can be further insulated to prevent the liquid from condensing. The conveying pipe has the advantages of simple structure, convenience in replacement and suitability for industrial popularization.
Description
Technical field
The invention belongs to chemical industry tubing field, especially relate to a kind of heat-preserving anti-freezing liquid delivery tube.
Background technique
Chemical industry is often used tubing conveying material, but a lot of industrial chemicals has the solidifying point of oneself, is difficult for carrying at lower temperature, otherwise easily occurs the accidents such as obstruction.
The conventional way of a lot of enterprises is that such shortcoming is that outward appearance is ugly in the coated one layer of heat preservation cotton of tube surfaces, and technique is loaded down with trivial details, sometimes also needs to change waste of manpower.
Summary of the invention
The object of this invention is to provide one simple in structure, reasonable in design, the liquid delivery tube of heat-preserving anti-freezing, is especially applicable to chemical plant transported material and uses.
Technological scheme of the present invention is: a kind of heat-preserving anti-freezing liquid delivery tube, is characterized in that: described delivery pipe is divided into three layers, and outermost surface is rock wool heat-preservation layer, described rock wool heat-preservation layer is by the mode of flange plate crimping, be fixed on outermost surface, mesosphere is full of antifreeze liquid, and innermost layer is fluid passage.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, rock wool heat-preservation layer is coated on outermost surface by the mode of flange crimping, only changes and need to open flange as need, are convenient to change, specious; Mesosphere is antifreeze liquid, can further intercept severe cold, prevents that liquid from solidifying; This pipe structure is simple, is convenient to change, and is adapted at chemical plant and promotes.

Embodiment
As shown in cross sectional representation as of the present invention in Fig. 1, a kind of heat-preserving anti-freezing liquid delivery tube of the present invention, it is characterized in that: described delivery pipe is divided into three layers, outermost surface is rock wool heat-preservation layer 1, described rock wool heat-preservation layer 1 is by the mode of flange plate 4 crimping, be fixed on outermost surface, mesosphere 2 is full of antifreeze liquid, and innermost layer is fluid passage 3.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the present patent application scope, within all should still belonging to patent covering scope of the present invention.
